I am quite new to IP telephony. I would be glad if someone could explain in detail what it means if an ip phone is single line, 2-line, 4-line, etc.
Thank you.
Leos,
This community does not provide technical support and is not staffed with technical support experts. I recommend you post this and future technical support questions to the Cisco Support Community (https://supportforums.cisco.com/index.jspa).
We do encourage you to participate in the Cisco Collaboration Community and to also join our Cisco Collaboration User Group program! In the community, we encourage your discussion/sharing around collaboration topics and Cisco Collaboration Solutions, including business and IT requirements, industry trends, process, culture/organization issues, how collaboration can be used to transform businesses, vendor selection, adoption, training, architecture, licensing, and product features/functionality. If you are a customer or partner, you can also join the user group program to be eligible for member-only events and influence product direction.
We hope to hear from you again.
